As one of the members of the R&D team which is working onthe development of a biosensor for ketoacidosis, you would like topropose a new biosensor that is based on the electrochemical mode.This biosensor is able to measure the level of ketone in blood. Thehigh levels of ketone in blood serum can cause life-threateningketoacidosis. The new biosensor comprises 3-hydroxybutyratedehydrogenase (3-HBDH) and graphene. 3-HBDH catalyses the followingreaction as shown below.

3-hydroxybutyrate (3-HB) + NAD+ → acetoacetate + NADH

(a) You are aware that a biosensor should have a chemicalrecognition element and a transducer. Describe the electrochemicalbiosensor that you plan to propose to the R&D team.

(b) Briefly explain the immobilisation of the chemicalrecognition element for the biosensor mentioned in question Q1
